Mount the Antenna
Mount the Antenna
Follow these steps to mount the antenna to the mounting
surface.
1. Place the antenna baseplate over the holes drilled in
the mounting surface and make sure the forward arrow
inside the baseplate points toward the bow and is
parallel to the vessel’s centerline.
Figure 20: Forward Arrow in Antenna Baseplate
2. Carefully lower the antenna onto the mounting surface
and ensure the mounting holes (and foam seals, if
used) are aligned.
3. Using a 7/16" socket/ratchet or nut driver, unlock the
three hex latches securing each of the antenna’s
service hatches (see
Figure 9 on page 9 ). Then gently
lower the hatches.
4. Apply a thin layer of the supplied anti-seize lubricant to
the threads of the four supplied 1/2"-13 bolts to
prevent galling.
5. At each baseplate mounting hole, place a 1/2" flat
washer on a 1/2"-13 bolt and insert the bolt into the
hole from above.

6. Secure each mounting bolt to the mounting surface
using a 1/2" flat washer and a 1/2"-13 lock nut from
below.
7. Tighten the mounting bolts in a cross pattern until the
four rubber feet on the baseplate are bottomed against
the mounting surface. KVH recommends that you
tighten the nuts to between 35 and 40 ft-lbs (47 and 54
N-m) of torque.
8. Disconnect the crane rigging.
IMPORTANT!
If the foam seals are used, do not reposition the
antenna laterally once the antenna’s foam seal has
made contact with the foam seal on the mounting
surface. If you need to reposition the antenna, lift the
antenna first to avoid damage to the foam seals.
CAUTION
Be sure to observe the safe handling
instructions in the Material Safety Data Sheet
(MSDS) provided with the anti-seize lubricant.
